The holiness of God is immeasurable. He is pure, righteous, perfect, and desires to have a relationship with mankind, created in His image. While in the Garden of Eden, Adam and Eve were able to live in true freedom and sweet relationship with God. In Genesis 3, sin separated them, and the punishment for sin was imputed. Because of the darkness and depravity of sin, a sacrifice of blood was then required for cleansing and atonement. Leviticus 17:11 says, “For the life of the flesh is in the blood; and I have given it to you upon the altar to make an atonement for your souls: for it is the blood that maketh an atonement for the soul.”
Because God loved us and wanted to be in relationship with us, He provided standards by which sacrifices of atonement could be made. The blood of animals was shed throughout the Old Testament as sacrifices for sin, but a perfect sacrifice was never available until God gave His only Son, Jesus Christ. John 3:16 says, “For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.”
Love ran red on the cross of Calvary as Jesus shed His precious blood to pay the sin-debt for all mankind. Romans 5:8 tells us, “But God commendeth his love toward us, in that, while we were yet sinners, Christ died for us.”
God, the author and creator of life, displayed his love for us through the shed blood of his only Son, Jesus Christ, forever designating red as the color of love.
